IMPROVEMENT IN FRUIT-JARS.

Specification forming part of Letters Patent No. 194,617, dated August 28, 1877; application filed J une 4, 1877.

To all whom it may concern:

Be it known that I, HIRAM PURDY, of Burlington. in the county of Des Moiues and State of Iowa, have invented a new and useful Improvement in Fruit-Jars, of which the following is a specification:

The figure is a side view of a fruit-jar to which my improvement has been applied, partly in section to show the construction.

The object of this invention is to furnish fruit-jars which shall he so constructed that they may be closed perfectly air-tight, and which will allow their covers to be easily removed. a

The invention will first be described in connection with the drawing, and then pointed out in the claim.

A represents the body of a fruit-jar, the

, neck of which is contracted or drawn in so as to form an inwardly-projectin g edge, (1, around its mouth.

B is the cover, which fits into the mouth of the jar A, is tapered, and has a wide shallow groove lornled around it to receive the rubber band or packing U. In the cover B, directly opposite the inwardly-projecting edge a of the mouth of the jar A, is formed a narrow groove,

b, into which the edge a presses the band C, so as to make the jar perfectly air-tight. In

' the side of cover B, just above the groove N, is formed an air-hole, D which air-hole is a covered and closed by the hand 0.

. The jar is closed by pressing the cover B down into place while the contents of the said jar are hot, and have thus expelled the air.

To open the jar, the upper edge of the band C is drawn down to uncover the air-hole b and allow air to enter the jar. To enable this to be conveniently done, a notch, b', is formed in the flange of the cover B, directly above the air-hole b The cover B is then drawn to one side, which forces the edge a into the groove 1), and allows the other side of said cover to be raised.

1 claim as my invention- The air-hole b formed in the cover B just above the groove b, and covered with the packing-hand (J, substantially as herein shown and described.
